- Q: Is there a big difference between two high alumina brick and one high alumina brick?
- The difference between the two kinds of high alumina bricks is great. I perennial in Zhengzhou was responsible for the production and sale of colt refractories
- Q: What are the high aluminum bricks made of?
- The amount of refractory mud accounts for about 6% of the brick weight
- Q: What is the difference between corundum and high alumina??
- The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.
- Q: What are the requirements for Rubble backfill height?
- 1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.
- Q: Application characteristics of high alumina brick
- Load softening temperature. The softening temperature of high alumina brick products decreases with the increase of silica and alkali metal oxide content, but is higher than that of clay brick products, which is about 1420 - 1530 degrees centigrade. Al2O3. The softening temperature of corundum brick with content greater than 95% can reach above 1600 DEG C.
- Q: What materials are used for roof insulation?
- There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.
- Q: What are the requirements for refractory materials in heat treatment furnace?
- Refractoriness is the property of a refractory against high temperature, which means the temperature at which a refractory is softened to some extent after heating, but not its melting point. According to the degree of refractory, refractory materials can be divided into: General refractories, refractory degree is 1580 to 1770 DEG C; advanced refractories, refractory degree is 1770 to 2000 DEG C; special refractory material, refractory degree is greater than 2000 DEG C.
- Q: What is the apparent porosity of high alumina brick?
- Total porosity is porosity refers to the total volume of sample porosity in the percentage of total volume of samples. Apparent porosity refers to the percentage of the total volume of openings, pores, and total specimens in the sample.
- Q: How are the grades of high alumina bricks differentiated?
- High alumina brick: aluminium silicate refractory product with a content of three Al2O3 (two) and more than 48%
- Q: Which thermal shock stability of clay brick and high alumina brick is good?
- High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
